Marion Thurnauer to Head Argonne National Laboratory's Chemistry Division Marion Thurnauer (CHM) has been appointed director of the Chemistry Division for Argonne National Laboratory. Comprised of approximately 100 employees, the Chemistry Division conducts research in the fields of: electron transfer and energy conversion, radiation and photochemistry, photosynthesis, photoionization, metal cluster chemistry, chemical dynamics, coal chemistry, chemical separation science, heavy element coordination chemistry, heavy element photophysics and photochemistry and f-electron interactions, surface science, and organic superconductors. Thurnauer received her Ph.D. in chemistry from the University of Chicago and came to the laboratory in 1974 as a postdoctoral appointee in the Chemistry Division's photosynthesis group. She was named assistant chemist in 1977, chemist in 1981 and senior chemist in 1991. Since 1993 she has been Group Leader for the Division's Natural Photosynthesis Group. She has authored nearly 70 publications including journal articles and book chapters, primarily on the subject of solar energy conversion in natural and artificial photosynthesis. She is a member of the American Chemical Society; the Biophysical Society; Iota Sigma Pi and Sigma Xi. She is past president of the Association for applied catalysis A: General
Women in Science, Chicago Chapter. Her honors include receiving the University of Chicago Award for Distinguished Performance in 1991; the Agnes Fay Morgan Research Award from Iota Sigma Pi, the National Honor Society for Women in Chemistry; the Award of Merit from the Chicago Association of Technological Societies; the Argonne Director's Award in 1990 for extraordinary effort in organizing the Science Careers in Search of Women Conference; and a NATO Grant for International Collaborative Research at Freie Universit&t Berlin in West Germany in 1984. She was a key player in the development of the laboratory's Women in Science and Technology Program (MMIST) in 1990. From October of 1992 to October of 1994, she served as the WlST program initiator and currently sits on the WlST steering committee. She also helped in the creation and development of the Science Careers in Search of Women conference - - an annual event which reaches 400 young women from the Chicago area each year and encourages them to consider pursuing scientific and technical careers. BARBARA WARREN Rick Herman Named ZCSS Executive Director Richard G. Herman has been named as Executive Director of the Zettlemoyer Center for Surface Studies at Lehigh University. Herman, principal research scientist, has been a member of the Zettlemoyer Center for 20 years and will continue his research in catalysis and surface science.

has over 80 publications and has given over 100 seminars and professional presentations centered on catalysis, principally on the preparation of catalysts and synthesis of alcohols and ethers. He has also received four U.S. patents for developing new catalysts that can be used in processes for synthesizing chemicals from HECO synthesis gas obtained from coal or natural gas. Herman earned his bachelor's degree from SUNY at Fredonia and his doctoral degree from Ohio University. Before coming to Lehigh, he served as a postdoctoral research fellow at the University of Lund (Sweden) in inorganic chemistry and at Texas A&M University in physical chemistry. He served as president of the Lehigh Valley Section of the American Chemical Society in 1989 and currently serves as an alternate councillor. He was editor of the book on "Catalytic Conversions of Synthesis Gas and Alcohols to Chemicals" in 1984. In 1991, he received the Outstanding Achievement Award from the Fredonia State Alumni Association.
Recent Polish Articles In an article entitled "The synthesis and applications of the titanium-silicalite catalyst" [Chemik, 48 (1995) 251], E. Milchert and L. Tarachowicz have discussed the main applications of titanium-silicalite catalyst (TS-1). In addition, methods for the synthesis and activation of aTS-1 catalyst with increased titanium content are presented. The paper contains 65 references. In the same issue, in a paper entitled "Causes of industrial vanadium catalysts destruction in the view of laboratory investigations" [Chemik, 48 (1995) 258], P.

Grzesiak, T. Gapinska, G. Schroeder and F. Domka have presented the results of physicochemical investigations of newly prepared and destructed catalysts. They suggest a possible mechanism responsible for the catalysts' decomposition. These investigations were initiated as a result of the fact that in the years 1992 and 1993, severe physical deterioration of the vanadium catalyst used in three domestic H2SO4 production plants took place.

Russian Literature In an article entitled "The structure and catalytic mechanism of methane monooxygenase and approaches to its modelling" [Russ. Chem. Bull., 44 (1995) 10tl], A.A. Shteinman has discussed the mechanisms of O and CH4 activation by the enzyme methane monooxygenase (MMO). He has proposed a new concept of the MMO catalytic cycle. Approaches to MMO modelling are considered critically. In a paper entitled "Effect of aging of ammonium-exchanged forms of zeolite Y by IR data" [Russ. Chem. Bull., 44 (1995) 1021], L.S. Kosheleva and M.A. Shubaeva have studied by means of IR spectroscopy the changes in the structure of ammoniumexchanged forms of zeolite Y observed after prolonged exposure to an air atmosphere. They have found that the distribution of cations in freshly prepared samples does not correspond to the equilibrium state: in the course of time, cations migrate to the most energetically stable sites. The authors have also observed a partial decomposition of the NH4 + form to a degree not exceeding 3-6%. These processes result in a decrease in the ionic character of Volume 132 No. 2 -
